Adventures With Linux ™ Posted on by

Just tested Kernel 3.17-rc3, and it breaks VMware (10.0.3) – vmnet: ……………. /tmp/modconfig-d0zqLW/vmnet-only/netif.c: In function ‘VNetNetIf_Create’: /tmp/modconfig-d0zqLW/vmnet-only/netif.c:152:64: error: macro “alloc_netdev” requires 4 arguments, but only 3 given     dev = alloc_netdev(sizeof *netIf, deviceName, VNetNetIfSetup);                                                                 ^ /tmp/modconfig-d0zqLW/vmnet-only/netif.c:152:10: error: ‘alloc_netdev’ undeclared (first use in this function)     dev = alloc_netdev(sizeof *netIf, deviceName, VNetNetIfSetup); …………… Thanks to Erwin Zoer (see … Continue reading →

Skype / Linux – When the Fix Becomes the Problem.. (Updated)

Adventures With Linux ™ Posted on by

I have been running a ‘fixed’ version of Skype on my Linux systems for some time (Fedora 20, x86_64), which included ‘PULSE_LATENCY_MSEC=30’ in a skype script to run the executable (skype-bin).. Recently, I have experienced garbled and ‘sped up’ sound, and this was easily demonstrated using the Skype Test Call facility.. The solution to this used to … Continue reading →

Adventures With Linux ™ Posted on by

Just took delivery of one of a CuBox-i4-PRO, with quad-core i-MX6 1Mhz CPUs and 2GB memory built in.. CuBox-i4-PRO (with Odroid in the background..) The device comes with Android on a 4GB SD card, and I discarded this and – for testing purposes – used an old 16GB SD card and installed Fedora 20 on it. Some … Continue reading →

ARM – Odroid U3 to 3.14-rc3, but USB Fail..

Adventures With Linux ™ Posted on by

After a lot of ‘hacking’, I managed to get the Odroid U3 to boot with Kernel 3.14-rc3, from http://git.prahal.homelinux.net/odroid.git/ , but there were persistent issues with USB, which refused to recognise any devices connected (apart from the USB memory stick (usb-storage) connection built-in to the kernel at compile time). Fedora release 20 (Heisenbug) Kernel 3.14.0-rc3 on an … Continue reading →

NVIDIA – New Driver – Kernel 3.13 Fail..

Adventures With Linux ™ Posted on by

NVIDIA have just released driver 334.16, but – despite the fact that Kernel 3.13 has been released for some time now – the driver still fails to load correctly, with the same ”Unknown symbol acpi_os_wait_events_complete (err 0)” error.. So, the existing known/good kernel 3.13 patch still applies, except that the section of the patch relating to /uvm/nvidia_uvm_linux.h … Continue reading →

Audacity – Simple ffmpeg Compile Fix..

Adventures With Linux ™ Posted on by

The ‘binary’ version of audacity supplied by certain distros lacks functionality, due to patent issues, so the best option is to compile it yourself.. For some time, there have been compatibility issues at compile time between the latest released versions of audacity and ffmpeg, on many systems.. For audacity version 2.0.5, on my systems (Fedora 20) the … Continue reading →

NVIDIA – Possible Kernel 3.14 Patch..

Adventures With Linux ™ Posted on by

There is an article on DevZone that includes a possible Kernel 3.14 patch, from s_molgaard, for driver 331.38:  https://devtalk.nvidia.com/default/topic/683534/linux/331-38-on-3-14-rc1-kernel/ The patch format is – apparently – for kernel boot-time patching using dkms, which I don’t use..   So..  I just manually applied the changes shown for nv-linux.h to the Kernel 3.13 patch mentioned in my previous article https://rglinuxtech.com/?p=1032, … Continue reading →

Adventures With Linux ™ Posted on by

There have been several ‘Kernel 3.13’ patches on various sites for the latest NVIDIA drivers, and I have finally found one that – on my system – actually works, without causing uvcvideo / usb problems (see previous articles..)
